1 .铲蹚甜菜要三铲三蹚,起高垄。做到铲前蹚一犁,疏苗、定苗前各铲一次,疏苗、定苗后各蹚一犁,封垄前结束铲蹚。底肥不足或播种时未施氮肥地块,在最后一次蹚地之前应进行追肥(硝铵每公顷250—300公斤或尿素每公顷100—150公斤)。起垄要高,形成张口垄,做到铲地不伤苗,蹚地不压苗。 2.保护功能叶片保持功能叶片完整。擗叶片会降低甜菜的产量及含糖率,若一株甜菜擗叶片15—20个,会降低产量15-30%,降低含糖率1-3%,因此,应杜绝人为擗叶片。 3.拔大草及时拔净田间大
1. Bucket trip beet three times three shovels, from the high ridge. To make a shovel before the trip a plow, sparse seedlings, Dingmiao shovel once, sparse seedlings, Dingmiao trip after a plow, seal ridge before the end of shovel trip. In the case of under-fertilizers or un-fertilized plots, top-dressing (ammonium nitrate, 250-300 kg per hectare or urea, 100-150 kg per hectare) should be applied prior to the last trip. Ridging should be high, the formation of Zhangkou ridge, so shovel does not hurt the seedlings, not to pressure seedlings. 2. Protection function leaves to keep the function leaves intact. Leaves will reduce sugar beet yield and sugar content, if a beet leaf of 15-20, will reduce the yield of 15-30%, reducing the sugar content of 1-3%, therefore, should eliminate the man-made leaves. 3. Pull the grass in time to clear the field
